Three Words That Strike the Vital Point is the famous seminal statement by Garap Dorje that is said to encapsulate all the myriad dzogchen tantras. The key instructions on it by Patrul Rinpoche--the verses known as "The Special Teaching of Khepa Shri Gyalpo"--form the basis for the discourse in Primordial Purity. It explains that in dzogchen, when one has fully recognized that all the confusion of samsara is the expressive power of great emptiness, confusion is spontaneously liberated into the primordial purity of mind's essential nature. Compassion spontaneously arises, accomplishing the benefit of sentient beings. Dilgo Khyentse Rinpoche illuminates this beautifully in this profound work, which will inspire students of Buddhism and deepen their experiential appreciation of the teachings.
